Sept. 2009: In an effort to stem the rising tide of violence caused by Mexican drug cartels, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) Phoenix office begins its controversial Operation "Fast and Furious."The idea is to encourage gun dealers to sell to suspected traffickers for Mexican drug cartels and see where the guns end up.
